Bug #18166: integer != autocasted double

From: php@triplefusion.net Operating system: Windows NT 5 PHP version: 4.2.1 PHP Bug Type: Math related Bug description: integer != autocasted double I've ran into a bit of trouble trying to implement Blowfish in PHP- I've successfully ported a C implementation, and implemented a test-vector test in both languages. The output (needs a fixed-width font) might speak for itself: C Blowfish test: Result Key L indata L result R indata R result L indata L result R indata R result Success 0000000000000000 000000ff 00000000 00000000 00000000 00000000 4ef99745 4ef99745 6198dd78 Success ffffffffffffffff 00000000 ffffffff ffffffff ffffffff ffffffff 51866fd5 51866fd5 b85ecb8a Success 3000000000000000 00000011 10000000 10000000 00000001 00000001 7d856f9a 7d856f9a 613063f2 Success 1111111111111111 00000023 11111111 11111111 11111111 11111111 2466dd87 2466dd87 8b963c9d Success 0123456789abcdef 00000011 11111111 11111111 11111111 11111111 61f9c380 61f9c380 2281b096 Success 1111111111111111 00000000 01234567 01234567 89abcdef 89abcdef 7d0cc630 7d0cc630 afda1ec7 Success 0000000000000000 000000dc 00000000 00000000 00000000 00000000 4ef99745 4ef99745 6198dd78 Success fedcba9876543210 000000a1 01234567 01234567 89abcdef 89abcdef 0aceab0f 0aceab0f c6a0a28d Success 7ca110454a1a6e57 00000031 01a1d6d0 01a1d6d0 39776742 39776742 59c68245 59c68245 eb05282b Success 0131d9619dc1376e 000000a1 5cd54ca8 5cd54ca8 3def57da 3def57da b1b8cc0b b1b8cc0b 250f09a0 Success 07a1133e4a0b2686 00000049 0248d438 0248d438 06f67172 06f67172 1730e577 1730e577 8bea1da4 Success 3849674c2602319e 000000b9 51454b58 51454b58 2ddf440a 2ddf440a a25e7856 a25e7856 cf2651eb Success 04b915ba43feb5b6 00000013 42fd4430 42fd4430 59577fa2 59577fa2 353882b1 353882b1 09ce8f1a Success 0113b970fd34f2ce 00000070 059b5e08 059b5e08 51cf143a 51cf143a 48f4d088 48f4d088 4c379918 Success 0170f175468fb5e6 00000029 0756d8e0 0756d8e0 774761d2 774761d2 432193b7 432193b7 8951fc98 Success 43297fad38e373fe 000000a7 762514b8 762514b8 29bf486a 29bf486a 13f04154 13f04154 d69d1ae5 Success 07a7137045da2a16 00000068 3bdd1190 3bdd1190 49372802 49372802 2eedda93 2eedda93 ffd39c79 Success 04689104c2fd3b2f 000000d0 26955f68 26955f68 35af609a 35af609a d887e039 d887e039 3c2da6e3 Success 37d06bb516cb7546 00000008 164d5e40 164d5e40 4f275232 4f275232 5f99d04f 5f99d04f 5b163969 Success 1f08260d1ac2465e 00000040 6b056e18 6b056e18 759f5cca 759f5cca 4a057a3b 4a057a3b 24d3977b Success 584023641aba6176 00000058 004bd6ef 004bd6ef 09176062 09176062 452031c1 452031c1 e4fada8e Success 025816164629b007 00000079 480d3900 480d3900 6ee762f2 6ee762f2 7555ae39 7555ae39 f59b87bd Success 49793ebc79b3258f 000000b0 437540c8 437540c8 698f3cfa 698f3cfa 53c55f9c 53c55f9c b49fc019 Success 4fb05e1515ab73a7 000000e9 072d43a0 072d43a0 77075292 77075292 7a8e7bfa 7a8e7bfa 937e89a3 Success 49e95d6d4ca229bf 00000083 02fe5577 02fe5577 8117f12a 8117f12a cf9c5d7a cf9c5d7a 4986adb5 Success 018310dc409b26d6 00000058 1d9d5c50 1d9d5c50 18f728c2 18f728c2 d1abb290 d1abb290 658bc778 Success 1c587f1c13924fef 00000001 30553228 30553228 6d6f295a 6d6f295a 55cb3774 55cb3774 d13ef201 Success 0101010101010101 0000001f 01234567 01234567 89abcdef 89abcdef fa34ec48 fa34ec48 47b268b2 Success 1f1f1f1f0e0e0e0e 000000fe 01234567 01234567 89abcdef 89abcdef a7907951 a7907951 08ea3cae Success e0fee0fef1fef1fe 00000000 01234567 01234567 89abcdef 89abcdef c39e072d c39e072d 9fac631d Success 0000000000000000 000000ff ffffffff ffffffff ffffffff ffffffff 014933e0 014933e0 cdaff6e4 Success ffffffffffffffff 00000023 00000000 00000000 00000000 00000000 f21e9a77 f21e9a77 b71c49bc Success 0123456789abcdef 000000dc 00000000 00000000 00000000 00000000 24594688 24594688 5754369a Success fedcba9876543210 00000000 ffffffff ffffffff ffffffff ffffffff 6b5c5a9c 6b5c5a9c 5d9e0a5a 34/34 tests succeeded.

Failure number refers to the first L or R column pair that failed - they should be identical. In the PHP test, ( ) refers to the first letter of it's gettype() result- integer or double. Looking at this it seems PHP doesn't seem to allow that int == float, but allows to print them, and then they turn out equal. Also, you will note the PHP and C values are very different, although the code is nearly exactly the same - I can't figure out what causes this, but since the results seem to be OK, it does not seem to matter :| I'm not going to post my huge (20 kb) script here, but I'll send it if anyone needs to see it. -- Edit bug report at http://bugs.php.net/?id=18166&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=18166&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=18166&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=18166&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=18166&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=18166&r=support Expected behavior: http://bugs.php.net/fix.php?id=18166&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=18166&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=18166&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=18166&r=globals
